      No, sorry - I'm not able to edit the subject line, unfortunately. It went to a very good home though - someone well known in the audio community!

        Hello,

        For anyone wanting a VERY capable subwoofer at a great price: I have a JBL LSR6312SP ported 12" studio subwoofer, with the really nicely engineered split-gap neodymium motor that JBL uses in their highest end woofers. Caveats: amplifier is blown, cabinet is in rough shape, and the driver has the dust cap mushed in. Benefits - price! Looking for a firm $185 for the cabinet with driver and blown amplifier, and an outboard Audio Control Architect Model 100 which has an INCREDIBLY CONVENIENT adjustable subsonic high-pass PERFECT for rolling off below the port tuning frequency. The amplifier is rated at 210 watts RMS @ 2 ohms, but using a single channel (not bridged) should allow for a bit more. The factory amplifier is 250 RMS so it's fairly close.

        http://www.jblpro.com/www/products/r...ries/lsr6312sp

        This is DEFINITELY local pickup only (zipcode = 90042) as it's big, heavy, and bulky.

        Cheers,
        Tal

          June bump!

          Happy June everybody - this'll be the last one without the mitigating effects of La NiƱa so we should enjoy the "good" weather before next year's delivery!

            Some additions: all for local pickup in Los Angeles only! All prices firm.

            Have a HSU VTF-2 (original, not mark 1/2/3) subwoofer with a dead amp. Is a well designed ported 10" sub in a solid cabinet, that had variable tuning via the amp based on plugging zero, one, or both ports. Amplifier has dead power transistors, so not worth fixing, but has a good transformer, etc. Looking for $25 for the sub as is (you can use with an external amplifier) or $95 with a Dayton SA-240 which fits the amplifier cutout almost perfectly.

            Have a dead JBL LSR6312SP studio ported 12" subwoofer. This has the really really nice split-gap JBL 252F differential drive motor (cast frame, kevlar cone, neodymium motor, picture here: https://skelbiu-img.dgn.lt/1_5_60964...bl-252f-12.jpg) that works really well in this enclosure. The driver is unique in that it's a 2 ohm driver, optimized for the partnering amplifier. Looking for $85 for the box/driver combination (driver dust cap is ripped a little, works fine), or $135 with an AudioControl Model 200 stereo amplifier that is 2 ohm stable (80/175/210 RMS @ 8/4/2 ohms) AND has an adjustable high-pass filter (3rd order, from 20 Hz. on up) that is KINDA PERFECT for this subwoofer!

            Have a harmon/kardon AVR520 receiver I was using with a MiniDSP for active crossover projects as it has inputs directly into all 5 channels of the power amplifier (see here http://img.ukaudiomart.com/uploads/l...on-avr-520.jpg). Amplifier is rated at 75/100 watts into 8/4 ohms. Looking for $55 for this - is perfect for any 2 way active crossover projects!

            Have a JBL SB210 pro-audio 2 x10" ported subwoofer with a damaged box. Has two high power, aluminum/ceramic 4 ohm 10" drivers, looking for $73, T/S below

            Re 3.32 ohms

                Hi! Do you have any info on the EA 18" passive? I can't find any online.

                Thanks!

                  Ask and ye shall receive!

                  Fp: Resonance frequency (in free-air with no added mass) 20.5 Hz
                  Qmp: Mechanical compliance loss 6.8
                  Mmp: Moving mass 300g
                  Cms: Suspension Compliance 0.20 mm/N
                  Vap: Stiffness of driver scaled by cone size 391L
                  Sd: Area of the cone 1182 cm^2 Suspension Travel 35-38mm one way. Somewhere around 70- 76mm peak-peak, depending on how far you stretch the suspension.

                  The Mass Kit consists of a 120mm bolt, washers, lock washers and extra nuts to thread down the bolt, holding the mass disc in place. Each disc is approximately 96g. The bolt assembly is approximately 48g so you can add mass to the system by adding the appropriate number of steel disc. Remember to add your Mmp starting mass (300g) to the total.
